Boeing Company (BA)

[Porgie Tirebiter]

I'm not saying that Boeing, as the certificate holder, doesn't have responsibility for the ultimate airworthiness of the design and manufacture of it's products.

However if the stock of an airplane manufacturer dropped 8% every time a thermal pane failed on a windshield, there wouldn't be any airplane manufacturers making airplanes anywhere in the world.

No one wants to hear that it's "normal" for parts to fail on an aircraft, but actually it is sort of "normal".
